MCAT Biochemistry UPDATED ACTUAL Questions and CORRECT Answers Amino Acids - CORRECT ANSWER- - Found in proteins - amino group, carboxylic acid, hydrogen atom, and R group attached to a central alpha carbon - chiral (L) except glycine - (S) configuaration except cysteine - join via peptide bonds Nonpolar, nonaromatic AA - CORRECT ANSWER- glycine

How many amino acids are incorporated into proteins? - correct answer 20 All amino acids exist in what form, EXCEPT for glycine? - correct answer L-form All amino acids are in L-form EXCEPT for what? - correct answer glycine Glycine is not in L-form because? - correct answer it doesn't contain a chiral carbon define chiral carbon - correct answer different compounds at each binding site All amino acids are what? - correct answer amphoteric define amphoteric - correct answer ca...

sucrose correct answer: glucose + fructose with a glycosidic bond simple monosaccharide correct answer: formula: (CH2O)n -simplest carbohydrates -have an aldehyde or ketone group sugars with a aldehyde have a prefix aldo- sugars with a ketone group have a prefix keto- -if a ketose, the ketone group is always at carbon 2- this decreases the amount of isomers that could form -made up of chiral carbons- allowing the sugars to form different isomers, leading to structural diversity (aldos...

Chem 219 Unit 3 Exam Questions With 100% Correct Answers Stereochemistry the study of the three-dimensional structure of molecules Stereoisomers Compounds with the same structural formula and connectivity but with a different 3D arrangement of the atoms in space. Enantiomers Stereoisomers that that are non-superimposable mirror images. Enantiomers have the same connectivity but different orientations (twist) of the four atoms or groups in 3D space. The two different forms of the chira...
